lSPECIFICATION forming part of Letters Patent No. 754,831,1dated March 15, 1904. I Application filed November 30, 1903. Serial No. 183,229. (No model.)

T0 @ZZ whom t may concern.:

Be it known that I, JOHN A. ABoL'r, a citizen of the United States, residing at Eldon, in the county of VVapello and State of Iowa, have invented certain new and useful Improvements in Wrenches; and vI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in tools or devices for applying or removing tirebolts to or from vehicle-wheels and for other purposes.

Theobject of my invention is to provide a simple, durable, and comparatively inexpensive device of this character which is adapted for work of various kinds and which will effectively hold a bolt against rotation and also revolve a nut to apply or remove it to or from the bolt.

With this and other objects in View the invention consists of certain novel features yof construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.A

In the accompanying drawings, Figure 1 is a side elevation of my improved device. Fig. 2 is an end elevation of the same. Fig. 3 isa sectional view through a portion of the device.

Referring to the drawings by numeral, 1 denotes a stock or handle-bar having an arm or shoulder-'brace 2 at its inner end and a handlegrip 3 upon one side adjacent to its'center. Upon the same side of said stock adjacent to its opposite or outer end is an arm 4., which extends parallel with the said stock and beyond its outer end. A transverse shaft 5 is journaled in suitable bearings in the outer end of said stock and in said arm and has an operating crankhandle 6 formed at one end and a gear 7 secured to its opposite end. Said gear meshes with a pinion 8, secured upon the outer end of atubular shaft 9, mounted to rotate in bearings formed in the end of said arm 4. The inner end of said tubular shaft 9 is formed with an enlarged head or chuck 11, having a square or polygonal socket 12, in which a nut-engaging device 13 is removably secured by a set-screw or other fastening means l14. The said nut-holder 13 is formed with an opening 15 to receive a nut and is made removable to permit it to -be replaced by similar holders having different-size openings, and thus adapt the tool for nuts of It will be seen that the head-- different sizes. or chuck 11 constitutes a revolving wrench, which when the crank-handle 6 isturned will bebrcftated to thread or unthread a nut upon a o t.

The bolt is held. against rotation while the Vnut is being revolved by providing a springformed intermediate its ends with an elongated opening 23, through which the shaft 5 extends. Ooactin g with the spring-arm adjacent to its inner end is a cam-lever 24, which is pivoted upon a bolt 25 between ears 26, bent up from a plate 27, secured to the stock 1. The spring-arm extends between said ears 26 beneath the lever 24., and when the latter is swung down to its released position-that is, with its cam portion out of engagement with the springarm-said arm will be permitted to spring away from the stock, and thus move the boltengaging claw away from the revolving wrench. When the lever is swung up so that its cam portion will engage the spring-arm, the latter will be forced inwardly toward the stock and will hold the claw 21 in engagement with the head of the bolt to prevent its rotation.

rIhe operation and advantages of my vinvention will be readily understood from the foregoing description taken in connection with the accompanying drawings. It willbe seen that when the device is used to apply or remove tire-bolts the stock is held by placing the brace 2 against one shoulder or under one arm, and with one hand upon the grip 3 the nut-holder is engaged with the nut upon the under side of the felly. The operator then uses his other hand to operate the lever 24 and clamp the claw 21'upon the head of the bolt. The crank-handle is then turned to revolve the nut to either remove it from the bolt or apply it to the same.A Since the arm 16 is made of spring metal, the claw will adjust itself upon bolts of different lengths Within a certain limit. Should, however, the bolt be unusually long or short, the claw is adjusted by means of the set-screw 22, as Will be readily understood.

From the foregoing description, taken in connection With the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, WhatI claim as new, and desire to secure by Letters Patent, is-

l.. The combination of a suitable stock or handle-bar, arevolving nut-Wrench mounted upon the same, a spring-armupon said stock,

an adjustably-mounted bolt engaging clawjournaled in said stock and forming a chuck,

a nut-holding device removably secured in said chuck, means for revolving said shaft, a spring-arm upon said stock, a bolt-engaging claw carried by said spring-arm, and a camlever for adjusting said spring-arm, substan tially as described.

3. The combination of a stock having an arm-brace, and a hand-grip, a tubular shaft journaled in said stool: and having a recessed head at one end, a nutholder removably secured in said head, a pinion upon the opposite end of said shaft, a crank-shaft, a gear upon said crankshaft meshing With said pinion, and a bolt-holding means carried by said stock and coacting with said nut-holder, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
